The invention discloses a power distribution method of a pure electric vehicle, and belongs to the technical field of pure electric vehicle energy management. The method comprises the following steps:1, establishing a control model; 2, defining a fuzzy subset; 3, determining a membership function; 4, formulating an inference rule; 5, selecting an inference method; and 6, selecting an ambiguity resolution method. In the invention, a cycle energy consumption rate of a whole vehicle working condition is effectively reduced, available output power of a power system is optimized, and long-time cycle power performance and economic performance of the whole vehicle are improved on the premise of not increasing or decreasing overall energy of a power battery.
本发明公开了一种纯电动汽车的功率分配方法,属于纯电动汽车能量管理技术领域。该方法包括如下步骤:步骤1:建立控制模型;步骤2:定义模糊子集;步骤3:确定隶属度函数;步骤4:制定推理规则;步骤5:选择推理方法;步骤6:选择解模糊方法。本发明有效地降低了整车工况循环能量消耗率、优化动力系统可用输出功率,在不增减动力电池整体能量的前提下,改善整车长时间周期的动力性能与经济性能。
